Load Balancing in OpenFlow Networks
Marciniak, Petr ; Ryšavý, Ondřej (referee) ; Grégr, Matěj (advisor)
The aim of this thesis is to develop a load balancing tool for OpenFlow networks. Software-defined networking (SDN) principles are introduced (OpenFlow protocol used as an example) and compared to the legacy routing and switching technology. Openflow is the first protocol/API enabling communication between the control and infrastructure planes of the software-defined networking model. Key features of the protocol are described and several OpenFlow controllers are introduced. Current best practices in computer networks load balancing are discussed as well. The load balancing application development process is described including the test laboratory setups - Mininet (SW) and OFELIA (HW). The application test results are evaluated and possible further enhancements to the program are discussed.

In the Traces of Leoš Janáček - Conversion of Speech to Music
Marciniak, Petr ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The aim of this bachelor thesis is to develop an application, which will automatically convert speech recording in WAV format to speech-melody-based music in MIDI format. At first, the problem is analyzed and the theoretical background is described. Basics of music generation from speech are introduced. Initial experiments like creation of the elementary melody, averaging of tones, syllables detection, etc. are discussed in order to establish, which of these techniques have a positive impact on the resulting music and therefore should be implemented in the resulting application. Basic criteria of beauty in music generation needed to be defined and different compositional techniques such as inversion of notes or tempo changes were investigated. Further, the implementation is described and user testing is evaluated. The conclusions are drawn and future directions of development are discussed. The user manual for the application as well as a "cook book" listing tools used in the application development can be found in the Appendix.
